Indonesian anti-drugs chief has proposed building a prison on an island guarded by crocodiles to hold death row drug convicts.

Anti-drugs Chief Waseso said that crocodiles would be better at preventing drug traffickers from escaping prison as they could not be bribed – unlike human guards. He visited various parts of the archipelago in the search for reptiles to guard the jail.

Indonesia already has some of the toughest anti-narcotics laws in the world with a moratorium on the death penalty having been abolished in 2013.

- We will place as many crocodiles as we can there You can’t bribe crocodiles. You can’t convince them to let inmates escape, Mr. Vaseso explained the choice of the future jailers.

The plan is still in the early stages, and neither the location nor potential opening date of the jail has been decided.
